Hi,

The title of this post implies that I know why airplanes fly. I
don't, not completely at least. But I do know that I have read a lot
of "official" explanations that are just plain wrong.

Before I begin my exposition about what keeps the plane afloat, I
would like anyone who care to participate in this discussion to do a
couple of simple experiments.


Good grief..
